Application led January 9, 191'?. Serial No. 141,356.

To all whom it may concern: v

Be it known that I, HARRY Osons VlTIN'rnu, a citizen of the United States, resliding at 2026 South Nineteenth street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and luseful Lock Hair-Pin, of which the following is a specification.

The purpose oit myv invention is to provide a double hair pin having parallel tines or prongs.

A further purpose of my invention is to provide a fiat double hair pin with locks 'Formed by oppositely placed gripping swells restricting both passages.

A further purpose of my invention is to -iol'ni the middle tine or prong of a double hair pin slightly longer than the outside tines or prongs for the purpose oi' facilitating entry of the hair pin into the hair and protecting the head from being scratched by the other prongs.

Further purposes will appear in the specification and in the claims.

I have preferred to illustrate my invention by but two among the various forms in which it may appear, selecting therefrom forms which are simple, inexpensive and effective and which well illustrate the principles of my invention.

Figures 1 and 3 are top plan views of hair pins embodying my invention.

Figs. 2 and 4 are side views of the forms shown in Figs. 1 and 3 respectively.

Similar numerals of reference indicate corresponding parts.

My hair pin is designed to have a maximum grippmg action upon the hair in both passages and for that reason is formed preferably with parallel outer tines, or prongs 5 and 6 having inwardly directed swells or "bends 7, 8, with which cooperate, outwardly directed swells or bends 9, 10 upon the members 11, 12 of the double inner tine orprong 13. Locks for the hair are thus provided holding both the hair and pins eii'ectively; Two of these locks are shown in each passage 1li, 15, resulting in the pin when in use being supported against withdrawal and against side movement by strands of hair at two points 16, 17 in each passage, these ppints being at or near opposite ends of the 1n. Y. P The bends `in the several prongs preferably lie within the same planes as the prongs themselves, securing a perfectly dat eect,

avoiding discomfort to the wearer and with a maximum locking effect for a given size of bend or swell.

The pin is perfectly dat in the form shown in Figs. 1 and 2.

The rounded point 18 of the middle tine or prong is projected longitudinally beyond the points 19, 20 of the outer tines or prongs in order to make it easier to insert the pin, into the hair, particularly useful because of the relatively blunted Vpoint of the middle tine or prong. 1t also protects the head from the points of the other and sharper tines or prongs. The extent of this projection need not be great.

ln Figs. 3 and 4 the reversely bent middle members 11, 12 'composing the inner prong are stiifened against lateral displacement by staggered connection with the outer prongs, z'. e. each outer prong is connected with that member` 11 or 12 which is the farther removed from it. The two are passed over each other preferably by oppositely directed partial bends 21 and 22 in the material of the prong close to the closed ends, giving an interlocking effect with a minimum of side gisplacement in each of the crossing memers.

It will be evident that the extension of the middle prong and the locking contribute to a very eiective double hair pin which is free from the objectionable characteristics of existing pins and which is improved in 3 its gripping qualities by having the projections within substantially the same plane as the body of the pin.

Having thus described my invention, what I claim as new and desire to secure by Let-V ters Patent is :M

1. A double hair pin having parallel side prongs uniting to form a central prong reversely turned at th'e Jfront end to form a point and there Tprojecting beyond the ends of the side prongs.

2. A double hair pin having a double cenl tral prong closed at the front end and side prongs and having the point of the central prong projecting longitudinally beyond the points of the side prongs.

3. A fiat double hair pin having side prongs crossed at the back of the pin and projecting forward substantially parallel throughout the greater part of their length to the front where they are united to form a middle prong point, the middle and side 'prongs having'oppositely-extending projections restricting the openings between and lying substantially in the planes of the body of the pin. y I

4. Adouble hair pin having substantially 5 parallel side prongs; a double central prong reversely bent at the front end to form a.

point and there extending longitudinally be other restricting the opening between the 1Iy prongs. y l y HARRY' OSCAR WINTER. Witness:
